You've had a long day. Your body aches. Your eyes are heavy. You get into bed — and then nothing. Your mind switches on like a light you can't turn off. You lie there for hours, exhausted but unable to sleep, and by the time morning comes you feel worse than when you went to bed.
This is one of the most common complaints I hear from students. And it makes complete sense once you understand what's happening in the nervous system.
When your cortisol levels are chronically elevated — which happens after sustained stress, anxious thinking, or simply scrolling through your phone in the hours before bed — your body stays in fight-or-flight mode even when you're physically exhausted.
Sleep requires your nervous system to shift into parasympathetic dominance. Your heart rate slows. Your breathing deepens. Your digestion activates. Your body temperature drops. None of this can happen if cortisol is still high. Your biology is fighting against your tiredness.
This is the single most powerful pose for sleep I have ever taught. Lie on your back and swing your legs up against a wall. Stay there for ten minutes — longer if you can. The reversal of blood flow towards the heart activates the vagus nerve and signals a parasympathetic shift. Cortisol drops. Heart rate slows. Sleep becomes possible.
Do this in your bedroom, in the dark, before you get into bed. No phone. No music. Just ten minutes of doing nothing. It will change your nights.
Place a pillow lengthways on your mat. Kneel and fold forward over it, resting your chest and belly on the pillow. Turn your head to one side. The compression on the belly stimulates the vagus nerve directly. The forward fold tells the brain: there is no threat. You can rest.
Five minutes minimum. Turn your head halfway through to release the neck evenly.
Lie on your back and bring the soles of your feet together, letting your knees fall out to the sides. Place cushions under each knee for support. Lay one hand on your heart and one on your belly. Breathe slowly — four counts in, six counts out. This extended exhale is the fastest way to activate your parasympathetic nervous system.
Your exhale activates the vagus nerve. The longer your exhale relative to your inhale, the stronger the calming signal. Try 4 in, 8 out for three minutes and notice what shifts.
Sleep isn't something you do. It's something you allow. And allowing it means creating the conditions — physical, emotional, neurological — that make it possible. These three poses won't just help you sleep tonight. Practised consistently, they will begin to retrain your nervous system so that the shift into rest becomes easier and easier over time.
